CLOTH ES-WRINGHER.

SPECIFICATION forming part of Letters Patent No. 707,974,datedAugust 26,1902.

Application filed July 17, 1399."

ing is a specification, reference being had to the accompanyingdrawings, in which- Figure 1 is a side elevation of a clothes wringerembodying my'improvements, and Fig. 2 an end view of the same withcertain parts removed to more clearly illustrate certain features of myinvention.

and Fig. 4 is a section on line4 40f Fig. 1. My invention relates toclothes-wringers of that type which comprise inconstruction a lowerdriving roll and an upper roll movably supported so as to permit fabricsof varying thickness to pass between said rolls, and said upperroll isusually pressed against the lower roll by means of a spring and isrotated by frictional contact with the lower roll or with the interposedfabric. 7.

My invention relates particularly to the lower roll and the drivingmechanism for said roll. The object of my invention is to construct aclothes-wringer with a hollow lower drivingroll and to provide a compactand simple driving mechanism for said lower driving-roll, part of whichis within and shielded by said hollow roll.

My invention is a clothes-wringer comprising a hollow driving-roll anddriving-mechanism for said roll, consisting of a shaft extending throughand free' to turn within said roll and operatively connected at one orboth ends with the roll and means for rotating the shaft within the rollto actuate the latter.-

Referring to the drawings, the lower. roll A is constructed from ahollow cylinder provided with an outer covering A, of rubber, and saidroll is supported by standards B B, in which it has its bearings. Thestandards B are each secured to abase B, which is provided with theusual clamps B connected thereto in the usual manner. Each standard B isconstructed with an aperture 1), which is larger in diameter than theoutside diameter Fig. 3isacenv has heretofore been necessary. trallongitudinal section on line 3 3 of Fig. 2,

of roll A, and within this aperture are located 'antifriction-rolls b,grouped around said roll A and occupying the space intermediate thewalls of said aperture and said roll A. The rolls 1) are held in placewithin the standards by means of retaining-rings b which are secured tothe standards B by means of screws Bythis' construction a very nearlyfrictionless bearing is provided for the roll A, and the power requiredto rotate said roll when the wringer is in use is much less than Thedriving mechanism for roll A'consists of a shaft 0,

, extending through and free to turn within the hollow roll A andjournaled in brackets o c, projecting upwardly from base B. One

end of shaft 0 projects slightly beyond its bracket 0 and has secured toit a crank-handle c, by means of which said shaft is operated. Mountedon shaft C are two pinions c 0 which are fixed thereto by means ofsetscrews c or otherwise, and said pinions are eachlocated near one endof shaft 0 and engage internal gears 0 the hubs c of which areinternally screw-threaded and screwed upon the eXternally-screw-threadedends of the roll A. By this arrangement and construction a convenientand compact driving mechanism is provided, the rotating gears of whichare inclosed, thereby preventing their accidental engagement withfabrics being operated upon by the wringer.

j Other features of construction shown in the drawings relating to theupperroll D are old andwell known, and detailed description of them isnot necessary.

i What I claim as'my invention is The improved clothes-wringer abovedescribed comprising wrin ger-rolls, one of which has a tubular shaft;apower-driven shaft inside the tubular shaft; and pinions on thepower-shaft meshing with internal gears 0n the tubular shaft whereby theclothes passing between the wringer-rolls are not exposed to the teethof the gearing.
